Principles, operation, and image reconstruction of computed tomography scanning systems.
About this course
Computed tomography (CT) has become one of the most widely used diagnostic imaging modalities in modern healthcare. This course explores the underlying physics, system architecture, and clinical applications of CT scanning. You will study how x-ray data is acquired from multiple angles and how sophisticated algorithms reconstruct cross-sectional images.
The curriculum covers both hardware components—such as the gantry, detector arrays, and high-voltage generators—and software aspects, including image reconstruction techniques and post-processing. You will also learn how to optimize scan parameters for different clinical scenarios, ensuring the lowest possible radiation dose for patients without compromising diagnostic quality.
